UNITED STATES PATENT OFFICE.

GEORGE O. F vATER, OF ST. LOUIS, MISSOURI.

Gas-PRODUCER.

- Specification of Letters Patent.

Patented March so, 1909.

To all whom it may concern:

Berit known that L'GEORGE C. F. VATER,

a citizen of the United States,'residing in the city of St. Louis,State of Missouri, have invented a new and useful Improvement in Gas-Producers, of which the following is a specification." v

The object'of this invention is the'produc- 'tion of a rich and uniform gas by uniformly 1 0 distributing theqair admitted into the producer, and afurther object is to utilize to'the best advantage/the fuel placed in the said producer, b supplyin to the said fuel an even "flow 0 .air, there y securing completeand uniformcombustion.

HThe invention relates especially to the form of grate employe and to the; manner of admitting air to the said grate.

" In'the accompanying drawings-Figure 1 is a :vertical" elevation through a producer with m'y grate and air pipe applied thereto;

'Fig.2is afplan view of the grate.

In these drawings, A represents the combustion chamber, the walls of. which are vformed; preferably of fire brick and from which extend'a gas pipe Af. Opal hoppers B and poke "holes B are also provided and these portions of the device are of the usual form. I also provide the usual water pan G into which the ashesfall and which forms a sill for'the lower end of the combustion chamber... The grate'D consists of a cylin-' drical casing arranged centrallyi in the water C and extending upwardly into the comu'stion chamber A The cylinder D sup ports-and opens into a cone 1) which is provided "withra, plurality of slots, the cone forming substantially upon its side a plurality .of

grate bars, the apex being closed or solid.

An anijpipe E is provided at its outer end with .a suitable steaminjector E and its inner endis provided with a suitable elbow which-connects it to the upwardly extendin pipe E which pipe is arranged centrally an E throughout the upper ortion ofits length is provided with a plura ity of erforations as shown at E. In use the ash ine is above apex of the cone and the upper coal line is adjacent the gas neck or pipeA. The air passing out o the perforations E will pass uniformly through the slots of the cone D and upwardly through the 'ashes'and fuel. This form of grate allows an even fall of the coal-line as the ashes are raked down, and also permits the ready withdrawal. of 'all clinkers which may coll'ect'in the roducer, the ashes, clinkers, etc. sliding rea ily down the cone-shaped grate into the water pan.

By means of a pioducerprovided with a grate of this description and provided with an air cylinder into which air is admitted through the perforation of the pipe E I am enabled to secure a rich and uniform gas, and also to utilize to the best advantage the fuel fed to thecombustion chamber A.

Havin thus fully described my inventio what I 0%). Letters Patent is In combination with a roducer having a combustion chamber and a water pan, a cylindrical air receptacle mounted centrally in said pan, an air pipe extending upwardly through the said air receptacle, a conical grate supported upon the receptacle and opening outwardly into the receptacle, said grate having a non-perforated apex portion, the said air pipe being perforated and having its upper end closed by the apex of. the

' cone, the perforations being in the horizontal plane of the grate openings as and for the purpose set forth. GEO. C. F. VATER.
